A recursive grep on /usr revealed that the file:


has sections that looks for 'mkl_lapack32' and 'mkl_lapack64'. I deleleted the
references to 'mkl_lapack64' and changed 'mkl_lapack32' to 'mkl_lapack',
and voila, numpy compiles! (after removing the 'build' directory in the
numpy root -- there will be errors if stuff is there from a prior attempt)

The numpy-1.0.1 RPM version is faster:

I wonder why that is?
